Brand loyalty and Isntree reputation
Multiple reviewers cite existing familiarity with the Isntree brand and its gentle formulation as primary purchase drivers, indicating strong brand equity in the market.
Influencer and word-of-mouth recommendations
Several reviews mention learning about the product through director/influencer recommendations (e.g., 'Director Pi'), and explicit positive word-of-mouth from consumers seeking sunscreen for oily skin types.
Multipack format and value
The +10ml×2ea bonus sizing appeals to repeat customers and those seeking travel-friendly portions, with reviewers noting satisfaction with the amount of product included.
Specific skin concern targeting (oily & sensitive)
Consumers purchased specifically because the product was recommended for oily skin or because they sought a non-irritating option for sensitive facial areas, including around the eyes.
